ELECTROMAGNETIC SYSTEM FOR OVERRUNNING COUPLING ASSEMBLY

摘要

An electromagnetic system for controlling the operating mode of an overrunning coupling assembly is provided. A control member is mounted for controlled shifting movement between coupling faces of coupling members and a stator structure including at least one electromagnetic source to create a magnetic force when energized. A magnetic or ferromagnetic translator structure is coupled to the control member for selective, small displacement, control member movement. The translator structure is magnetically coupled to the stator structure across an air gap and is supported for translational movement relative to the stator structure along a path between first and second stable end positions. The translator structure completes a path of magnetic flux to magnetically latch in at least one of the end positions and to translate along the path between the end positions upon experiencing a net translational force.
